June 30, 2022

Building house owners and facility administrators can make indoor environments safer by disinfecting indoor air, according to a new Op/Ed short article in The New York Times by airborne infectious disease experts Donald Milton, a University of Maryland professor of environmental well being, Edward Nardell of Harvard College and David Michaels of George Washington University.

A single of the very best technologies to do so — germicidal ultraviolet gentle — has been studied for decades and can now be applied safely.

GUV can very easily and silently kill 50 percent of the germs floating in indoor air each individual two minutes or significantly less. It was created and analyzed commencing in the 1930s making use of some of the same technologies in fluorescent light-weight fixtures. It is even now typically used in TB wards, as very well as some important clinic programs and homeless shelters.

The original expenses for products and set up of a hugely powerful GUV method can often be reduce than upgrading or changing ventilation systems. GUV also disinfects the air a lot quicker and with significantly significantly less electric power than ventilation and filtration, which usually means it’s a local climate-welcoming solution for superior-possibility environments.
